Mobile Data Terminal Systems
A Mobile Data Terminal, commonly called an MDT, is the digital backbone of any law enforcement roleplay system in FiveM. MDT scripts provide officers with a computer interface accessible from their patrol vehicle that displays active warrants, BOLO alerts, criminal records, vehicle registration information, and incident reports. A good MDT system integrates with your framework's player database to pull real character information, allowing officers to run name checks and plate lookups against actual player data. Popular MDT solutions include ps-mdt and custom-built systems, each offering different levels of detail and integration. The MDT should also support internal department management features like setting unit status, logging on-duty hours, filing incident reports, and managing the chain of command with rank structures and department transfers.
Dispatch and CAD Systems
Dispatch systems connect civilians who need help with the emergency services that can respond. When a player calls 911 or triggers an emergency, the dispatch system creates a call with location information, a description of the situation, and the caller's identity. Officers can then claim calls, update their status, and mark calls as resolved through the MDT or a dedicated dispatch interface. More advanced CAD (Computer-Aided Dispatch) systems provide real-time unit tracking on a map, automatic unit recommendation based on proximity, priority queuing for different call types, and integration with GPS routing to guide officers to the scene. Some servers use dedicated dispatch roleplayers who manage the radio and coordinate responses, while others automate the process entirely. The best approach often combines automation for routine calls with human dispatchers for complex situations.
Police Vehicle Equipment
Emergency vehicles in FiveM need specialized equipment scripts that go beyond basic vehicle spawning. Light bar controllers allow officers to cycle through different lighting patterns for traffic stops, code 3 responses, and scene management. Siren controllers provide multiple siren tones that can be toggled independently. Radar and LIDAR scripts let officers enforce speed limits with functional speed detection equipment. Spike strip deployment systems allow officers to disable fleeing vehicles. Dashcam and bodycam scripts record interactions for later review, which serves both roleplay immersion and administrative evidence collection. Vehicle-mounted computer terminals that display the MDT when sitting in the driver or passenger seat complete the patrol car experience. Each of these systems should be configurable per vehicle class so unmarked units have different equipment profiles than fully marked patrol vehicles.
Weapons and Equipment Systems
Law enforcement equipment systems manage the weapons, tools, and supplies that officers carry on duty. An armory script allows officers to check out their duty weapon, taser, body armor, first aid kits, and other standard issue equipment at the beginning of each shift. Weapon lockers at police stations should be restricted by department and rank, ensuring that patrol officers cannot access SWAT-level equipment without authorization. Evidence collection scripts let officers bag and tag items found at crime scenes, photograph locations, and submit evidence to the MDT for case files. Restraint systems including handcuffs and zip ties with proper animations and mechanics for detaining suspects are essential for any police roleplay. Each piece of equipment should integrate with your inventory system so officers physically carry their gear and can run out of consumables like ammunition or medical supplies during extended incidents.
EMS and Fire Department Scripts
Emergency Medical Services and Fire Department roleplay requires its own set of specialized scripts beyond what police systems provide. EMS scripts should include a medical system that tracks player injuries by body part, allowing paramedics to diagnose and treat specific conditions rather than simply pressing a heal button. Stretcher and gurney mechanics let EMS transport patients from the scene to the hospital, and ambulance interiors should include functional equipment for providing care during transit. Fire department scripts need functional fire propagation and suppression systems, hose mechanics with water physics, ladder truck operations for elevated rescues, and Jaws of Life tools for vehicle extrication scenarios. Both services benefit from shared dispatch integration so all emergency units operate within the same CAD system and can coordinate during large-scale incidents that require multi-agency response.
